It's not just Easter Sunday tomorrow - it's also the start of British Summer Time.
That means the clocks go forward by an hour at 2am and you'll lose an hour of sleep and valuable chocolate-scoffing time (but you'll get it back again when the clocks go back in the autumn).
So - don't forget to change your clocks this weekend.
The good news is that your smartphone, laptop or tablet already knows what to do, so just leave them to do their magic. But as for the cooker, the microwave and your alarm clock, you're on your own.
If you're having trouble trying to remember which way the clocks go, it's 'Spring forward - fall back'.
